Through its ongoing democratic practice involving a wide diversity of neighbourhood, city, etc. actors, it improves relations between individuals and organizations both within and outside the neighbourhood. Processes of SI are steered through socially 1&2 innovative governance [Mac Callum, D., et al. 2009]. In this regard, as mentioned earlier, we propose BATir Sustainability Research Tracks the establishment of a ‘European Social Innovation Network’. The following illustration shows how the philosophy of SI through IAD works: it reacts to deprivation or poor service provision, is based on the mobilisation of local and supra-local resources, and depends for its effectiveness on multi-scalar Prof. Ahmed Z.
